Spook seen around your university is rather sweet (6)
I believe the answer is:
syrupy
'rather sweet' is the definition.
'syrupy' can be an answer for 'sweet' (similar in meaning). I'm unsure of the 'rather' bit.
'spook seen around your university' is the wordplay.
'spook' becomes 'spy' (I've seen this in another clue).
'seen around' is an insertion indicator.
'your' becomes 'yr'.
'university' becomes 'u' (abbreviation for university).
'yr'+'u'='yru'
'spy' placed around 'yru' is 'SYRUPY'.
'is' is the link.
Can you help me to learn more?
(Other definitions for syrupy that I've seen before include "Like a sweet, sticky liquid" , "Excessively sentimental" .)
